What can I do if deltaddl gets it wrong?
There are sometimes things that deltaddl will get wrong, because it just doesn’t have quite enough knowledge or intelligence to work out what order to do things in, or because its understanding of SQL variants isn’t as good as it should be. If you run into such a problem, you’ll probably want to use –omit to leave out the offending object(s) or column(s), and add it manually to your own custom DDL script.
